Willy Tarreau 24ff1f8341 BUG/MEDIUM: mux-h2: make sure never to send GOAWAY on too old streams
The H2 spec requires to send GOAWAY when the client sends a frame after
it has already closed using END_STREAM. Here the corresponding case was
the fallback of a series of tests on the stream state, but it unfortunately
also catches old closed streams which we don't know anymore. Thus any late
packet after we've sent an RST_STREAM will trigger this GOAWAY and break
other streams on the connection.

This can happen when launching two tabs in a browser targetting the same
slow page through an H2-to-H2 proxy, and pressing Escape to stop one of
them. The other one gets an error when the page finally responds (and it
generally retries), and the logs in the middle indicate SD-- flags since
the late response was cancelled.

This patch takes care to only send GOAWAY on streams we still know.

It must be backported to 1.9 and 1.8.
